MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF file contains a large number of external links, identified as a link farm, which is a common technique for distributing malware or redirecting users to phishing sites. One of the embedded URLs, http://evacdir.com/absenteeism/..., is particularly suspicious and likely serves as a primary distribution point. The presence of numerous links suggests an attempt to obscure the ultimate malicious destination or to maximize reach.
